AJAX: dbmail - Email Client
The system consists of an underlying MySQL database which contains two tables; the users table (which contains the name, surname, user ID and password of
registered users) and the mail table (which contains the user ID, the mail ID, sender, subject, message body, date, and the mail status (read or unread)).
User log in - A simple login which allows already registered users to access their e-mail client. The user login allows users to enter their user ID and password in order to access their e-mail client. Once a correct user ID and password is entered, the user will have access to their inbox and will be able to send, receive and read e-mail.
